'7 Claims. (Cl. 221-64) This invention relates to powder dispensers. It is an object of the invention to provide a powder dispenser adapted to be mounted upon a wall or other convenient support operable automatically 5 to deposit powder along the bristles of a tooth brush upon mere insertion of the brush into the lower part of the dispenser.

It is a feature of the invention that provision is made of valve means for controlling the dis- IO' charge of powder from an inverted powder can and that mechanism is provided which is adapted to be engaged and driven by the body or back of the toothbrush for opening the valve to permit the powder to fall on the bristles of the brush.

15 It is a further feature of the invention that the valve is automatically returned to closed position as the brush is withdrawn. f

Other objects and advantages will hereinafter appear. .7

Fig. 1 is a fragmentary View in elevation,'partly broken away, illustrating a dispenser embodying features of the invention and having an inverted 25 powder can set in it;

Fig. 2 is a detail sectional view taken on the line 2-2 of Fig. 1 looking in the direction of the arrows;

Fig. 3 is a fragmentary perspective view show- 30 ing the powder can and the dispenser; and

Fig. 4 is a fragmentary view showing a detail of the mounting of the valve operating mechamsm.

A powder can I is shown in Fig. 1 as set in 35 inverted position in a dispenser 2. The dispenser comprises side body members 3 and 4 which are connected by a front plate 5 and a back plate 6. The back plate 6 is provided with flanged ears I which are adapted to be fitted onto headed screws 40 or other suitable supporting members secured in a wall.

The upper portions of the body members come together and jointly form a circular seat 8 upon which a shoulder of the can rests. They also oo- 45 operate to form a circular seat 9 upon which a funnel-like discharge spout I9 is rotatably mounted. The discharge spout II) has a circular opening in the upper portion thereof for receiving the mouth of the powder can. The discharge 50 spout is provided in the throat portion thereof with inclined ribs I2 for stirring the powder to prevent choking or clogging. A gear I3 is formed upon or aflixed to the exterior of the discharge spout I0 and is adapted to be driven by a pinion 55 I4 fixed upon the upper end of a shaft I5. The

26 in opposed relation to the ring 2I.

snugly against such sides.

shaft I5 carries a supporting collar I6 which rests upon a shelf I'I formed on the body member 4. Beneath the shelf I I provision is made of a valve plate I 8 fast upon the shaft I5 which normally covers and closes the exit opening at the lower I; end of the discharge spout I0. A spring I9 secured at one of its ends to the shaft I5 and at the opposite end to the body member 4 serves to retain the plate It normally in spout closing position. At the lower end of the shaft I5 provision i0 is made of a wheel ZBhaving a ring 2I of rubber or other suitable friction material secured upon it. The wheel 26 is secured througha spring 22 to a short shaft 23, the latter-being adapted to snap into a bearing recess in the bottom wall 24 of the body member 4. v V

The body member 5 is provided with a groove The ring 2| is provided with a corresponding groove 21. These grooves are adapted to embrace the opposite sides of the back of a toothbrush and fit The front plate 5 is provided with an opening 28 in the lower portion thereof in line with the passage between the grooved wall 26 and. the grooved ring 2I so that a toothbrush may be inserted into the device. When the toothbrush is inserted the grooved wall 26 causes the back of the brush to be pressed into frictional driving engagement with the grooved ring 2] so that the shaft I5 is turned against the 30 resistance of the spring I9. This turns the valve plate I8, causing it to uncover the exit opening of the discharge spout I0 and permits the powder to fall onto the brush. The pinion I4 at the same time drives the discharge spout through the gear I3 causing the stirrer blades I2 to agitate the powder. The inclination of the blades is such that they tend to force the powder downward as the toothbrush is thrust in.

The powder falls onto the toothbrush bristles so long as the valve plate is open. It is only necessary to thrust the toothbrush into the dispenser and immediately withdraw it in order to cause the desired amount of powder to be deposited. As the toothbrush is withdrawn the valve plate is returned to closed position and is retained in the original closed position by the action of the spring I9. I

In the assembly of the device the shaft I5 and the parts rotatable with it are assembled as a unit. They are then associated with the body member 4-, the shaft being inserted into a notch 29 formed in the shelf I1 and the pivot pin or shaft 23 being snapped into the recess 24. The body members 3 and 4 may next be connected through 5 7' the front and back-plates 5 and 6 by means of then be putinto place to complete the assembly. 7

'I do not, therefore, desire tolimit myself to the' specific constructions.illustrated, but intend to cover my invention broadly in whatever form its principle may be utilized.
